Abstract
Carbon nanotubes (CNTs) could be conductive or semiconductive anisotropic nanoparticles (NPs). Their ability to be oriented in liquid crystal (LC) cells generates a lot of interest among the scientific community. Control these conductive NPs alignment could enable the design of multiple applications, such as electrically controlled NP switches. The work that has been developed at the Università degli Studi di Napoli Federico II (Italy) consists of preparing liquid crystals doped with different types of carbon nanotubes and studying the mixtures using a Variable Angle Spectroscopic Ellipsometer (VASE). The goal is detect changes in the optical properties of the CNT-doped LCs (absorption, reflexion, etc?) depending on these NPs orientation. Furthermore, the study was completed with impedance and Raman spectroscopy measures. The CNTs employed are multi walled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs).
